Metal mold casting device using metal cope and metal drag and device for moving metal cope relative to metal drag

Abstract

A device for moving a metal cope towards and apart from a stationary metal drag, used in a metal mold casting device that uses the metal cope and drag, comprising: an upper die plate ( 9 ) for carrying the metal cope; a frame ( 5; 25 ); a metal mold opening and closing device ( 6 ) mounted on the frame for carrying and vertically moving the upper die plate relative to the frame so as to move the metal cope attached to the upper die plate between a position that is above and relatively near the metal drag and a position that is at the metal drag; and an actuator ( 3; 23, 23 ) connected to the frame for moving the frame so as to move the metal cope attached to the upper die plate between the position that is above and relatively near the metal drag and a position that is relatively far from the metal drag.

1. A device for moving a metal cope towards and apart from a stationary metal drag, used in a metal mold casting device that uses the metal cope and metal drag, comprising:
 an upper die plate for carrying the metal cope; 
 a frame; 
 a single upwardly-facing cylinder mounted on the frame for carrying and vertically moving the upper die plate relative to the frame so as to move the metal cope attached to the upper die plate between a first position that is above and relatively near the metal drag and a mold-closing position that is at the metal drag; and 
 an actuator connected to the frame for moving the frame so as to move the metal cope attached to the upper die plate between the first position and a second position that is relatively far from the metal drag; 
 wherein the single upwardly-facing cylinder is connected to the upper die plate through a lateral member and a plurality of vertical supporting rods suspended from the lateral member and slidingly passing through the frame guide vertical movement of the upper die plate. 
 
   
   
     2. The device of  claim 1 , wherein the actuator operates to allow the frame to rotatably move. 
   
   
     3. The device of  claim 1 , wherein the actuator includes a plurality of upwardly-facing cylinders for vertically moving the frame. 
   
   
     4. A metal mold casting device that uses a metal cope and a metal drag, comprising:
 a stationary metal drag; 
 a metal cope movable towards and apart from the metal drag, said metal cope defining a molding cavity in the metal cope and drag when mating with the metal drag; and 
 the device of  claim 1 . 
 
   
   
     5. The metal mold casting device of  claim 4 , wherein at least one of the metal cope and the metal drag is connected to means for supplying molten metal to the molding cavity, and wherein the means for supplying molten metal is a gravity-type supply means or a low-pressure-type supply means. 
   
   
     6. The device of  claim 1 , further including eject pins for pushing an as-cast product out of at least one of the metal cope and the metal drag. 
   
   
     7. The metal mold casting device of  claim 4 , further including eject pins for pushing an as-cast product from at least one of the metal cope and the metal drag.
